TILE-FORMING MACHINE.

Application filed July 21, 19 24.

To all whom it may concern:

Be it known that 1, JOHN Koinzox, a citizen .of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Tile-Forming Machines, of which the following is a specification.

This invention relates to tile niannfao ture and has special reference to a tile molding machine particularly adapted for the manufacture of terrazzo tiles suitable for floor and wall coverings and the like.

One important object of the invention is to provide a novel general construction of machine for this purpose wherein the material used for filling the molds is constantly jarred or shaken during the pressing operation. I

A second important object of the invention is to provide an improved arrangement of presser roll actuating means in such a machine A third important object of the invention is to provide an improved knocker operating mechanism for machines of this type.

A fourth important objectof the invention is to providea multiple mold tile machine having a novel jarring arrangement wherein the material in each of the several molds will receive individual jarring.

With the above and other objects in view as will be hereinafter apparent, the inven tion consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

In the accompanying drawings like characters of reference indicate like parts in the several views, and: t

platen 11. At each side of the platen and substantially on the level therewith is a guide rail 12 and on these rails run the wheels 13 of a pair of oppositely disposed carriages 14. each of which is provided at its upper portion with a suitable bearing 15 to receive the journal portion of a roll carrying shaft 16. On the shaft 16 between the bearings is fixed a pressing roller 1'? the bottom of which is spaced above the platen 11 to permit the roller to run on the upper surface of the reticulated mold 1& resting on a mold bottom plate 19 which is preferably of thin metal and rests on the platen 11, being properly positioned thereon by engagement with lugs 20.

At the rear end of the frame is a pair of bearings 21 wherein is journalled a shaft 22 which extends transversely of the frame and projects beyond the sides thereof to carry the rear end idler pulleys 23. Similarly there is provided at the front of the frame transverse shafts 24 which carry the idler pulleys 26. The ends of the shaft 16 project in like manner and are provided with belt pulleys 27 which are positioned above respective pairs of carriage idlers running freely on the stub shafts 29 fixed to the carriages 14. A belt 30 is provided on each side of the machine which is led around the various pulleys inthe manner shown in the drawings and which may he described as from one pulley 26 beneath one of the pulleys 28, up and over the pulley 27, down and beneath the other pulley 28, rearwar-dly and around the rear idler pulley and thence back to the other idler 26. It will be noted that, with this arrangement, the presser roller will be rotated irrespective of the position of the carriages so long as the shaft 24 is driven.

To drive the belt there is provided. in front of the frame a pair of bearings 31 wherein is journalled a jack shaft 32 which carries a belt pulley 33' around which the belt 30 passes. v has revolubly mounted: thereon a spaced pair of pulleys 36 provided with confronting clutch faces 37 between which is a double clutchimember '38, this clutch member 7 being splined on the shaft so that it maybe Furthermore the shaft 32 moved by the shipperle ver 39, which e115 gages} therewith, jinto. clutching engagement with one or the 'oth'eri of the pulleyjelutch faces'iand' thereby rotate the jack "shaft. "in a l t' f -ll.

s jack n ga itainy'shaft to 5' 57 *"whereon is iiitiunted a 51i$-*0fwfi$6ll- .iaabnspeng ""nm'ersltsequal 'insnuinher Ito thegcamsland ctuated'by tliecainfprejee- 1 .tio'ns, 'those"-hanimersbeing so l-arranged that supported in bearings 41 and driven from some suitable source of power not deemed necessary here to be shown. On the main shaft is keyed a pair ofpulleys 42 one of which is connected by a straight belt 43 with one of the pulleys 36 while the other pulley 42 is connected with the remaining pulley 36 by a cross belt 44. Thus by shifting the clutch the jack shaft can be driven in one direction or the other and this in turn will drive the presser roll in corresponding directions.

In order to effect automatic reversal of the presser roll after it has moved from the front to the rear of the machine alever 45 is pivoted to the frame at the rear and has its upper end projecting into the path of one of the carriages 14 so that, upon the carriage approaching the rearward limit of its movement,it will strike this lever and shift the same. Thus lever 45 is furthermore connected to the shipper lever by a linkage 46.

so that movement of the lever 45 effects movement of the shipper lever. These parts are so proportioned that the movement of the shipper lever disengages the central clutch member from one clutch face and engages it with the other.

In the operation of this part of the device the mold is placed on the platen and the clutch thrown in the proper direction to cause the roller, which at the start is slightly in front of the mold, to roll rearwardly upon its being started by moving the carriages back until the roller engages the mold. Then the roller rolls backward and runs over the mold pressing the mold contents down in the mold; Upon the carriage striking the lever 45 the rotation is reversed and the roller moves forward until it rolls off the mold whereupon the forward motion stops as the roller no longer contacts with any surfaceto roll thereover, the roller shifting thev clutch to neutral position at the same time.

The knocking or jarring mechanism comprises a lower longitudinal shaft 47 jour nalled in bearings 48 and carrying at its forward end a bevelgear 49 which meshes with a bevel gear 50 keyed on a jack shaft 50. On the shaft 47uare also fixed belt'j pulleys 51 which are connected by belts 52 with pulleys .53 on the cam shafts 54. In the main form of the device each'cam shaft is'proride-d with a series of cam wheels 55 each having a plurality of cam projections 56. Preferably there is. one cam shaft for each two longitudinalirows I of; molds and each cam shaft .hasacam wheel foreach transverse 1. row of molds in the multiple; mold, Parallel With eaclr'c'amshaft is a fi'Xedshaft each strikesitsblows centrally beneath a re spective mold. The shafts 57 may be ad justed to regulate force of the blows by moving them toward or from the cam shaft and this may also be effected by adjustment of the stop pins 59 in the slots 60 formed in the plates 61 which may be carried by the fixed shafts 57. Thus there is one hammer atingt-he entire set for the particularhammer shaft.

To drive the jack shaft 50 a belt 62 connects this shaft with the main shaft 40, the usual pulleys being employed. I

There has thus been provided a simple and efficient device of the kind described and for the purpose specified.

It is obvious that minor changes may be made in the form and construction of the invention without departing from the material spirit thereof. It is not, therefore, de sired to confine the invention to the exact form herein shown and described, but it is desired to include all such as properly come within the scope claimed.
